T0 a whont it may concern:

Be it known that I, ALBERT S. REED, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Adjustable Cones for BicyclelIubs, (Case No. 2,) of which the following is a full, clear, concise, and exact description.

My invention relates to ball-bearings, and has for its object to provide an improved cone having a flange which excludes dust and dirt from the hearings and which maybe adjusted to and fro upon the cone and be refitted as often as may be required.

Generally speaking, my invention comprises a bearing-cone having a body portion which is approximately cylindrical, although slightly tapered inwardly toward the bearing-surface, and a separate flange or washer associated therewith, having a disk portion for closing the mouth of the bearing-cup, and a cylindrical flange portion adapted to be fitted upon the approximately cylindrical part of the cone and to be adjusted thereon to fit any hub, as may be required. A cross-section of the body portion of the cone or of the cylindrical portion of the flange would be truly circularthat is to say, I do not flatten the cone, but depend entirely upon the tapered body portion to hold the adjustable flange with a tight drive fit. The simplicity of this construction makes it very cheap, and I have found in practice that it is convenient and effective.

My invention is illustrated in the accom panying drawings, in which Figure 1 is a sectional view of the end of a bicyclehnb equipped with my improved bearing-eone. Fig. 2 shows how the body portion of the cone may be fitted into the separate flange which it carries when in use. Fig. shows the cone and flange fitted together, and Fig. I is an end view of the hub shown in Fig. 1. I

Like letters of reference indicate like parts wherever they are shown.

The hub a has a bearing-cup b fitted in its end, said cup containing the balls 0 c in the usual manner.

My invention is concerned principally with the bearing-cone (Z and the flange e, carried thereby. The cone is screwed upon the shaft f of the hub until the bearing-surface d is in proper position to support the balls 0 c. The disk portion 6' of the flange should then be flush with the end of the bearing-cup to close the mouth thereof. Since the depth of the hearing-cup is not the same in all cases, a bearing-cone having a separate flange adjustable thereon is very useful to repairmen, since such a cone can be readily fitted to any huh. I have therefore made the body portion (Z of the hardened-steel cone substantially cylindrical, as shown in Fig. l, and pro= vide a separate flange e, of soft steel, having adisk portion (2' and a cylindrical flange portion 6 which is adapted to be fitted over the body of the cone.

I.have said that the body portion'of the cone was substantially cylindrical. It is not, however, exactly cylindrical, but is tapered very slightly from the outer end toward the bearing'surface d in order to make a good drive fit.

In Fig. 2 I have shown the cone entering the flange, which rests upon an annular metal block or anvil g. A perfect fit will be secured by tapping the top of the cone with a hammer, thus driving it down into the flange. It will be apparent that the flange may thus be adjusted to any desired position upon the body portion of the cone.

In Fig. 3 I have shown the cone and flange fitted together, ready to be applied to a hub. In practiceI make the flange of soft stee1,with the disk portion 6 thereof about as large as the mouth of the largest bearing-cup in common use. After a flange has been fitted upon a cone for a particularhub the repairman can turn down the flange in a few moments to fit exactly the mouth of that hub.

The adjustable cone of my invention has certain advantages over cones havinga flange screwed upon the body portion, since my flange may be fitted tightly and exactly and is not liable to work loose or change its position. My cone is also much cheaper to manufacture than such cones or others which have untapered body portions with flattened sides and washers movable thereon.
